About Me

I am a 5th year PhD student in the LASEC laboratory at EPFL, under the supervision of Prof. Serge Vaudenay.

Research-wise, I enjoy all sides of cryptography and security! My doctoral studies are focused on the algorithmic study of the Learning Parity with Noise (LPN) and the Learning With Error (LWE) problems.
